To all whom it'may coneemfl Be it known that 1, CHARLES H.jWAY, a citizen of the United States, and a'resident of the city of Lansing, i'n-the county of Inghani, 5 Stateof Michigan, have invented certain new and usefullmprovements in Governors for a s cification..

his inventionrelates to improvemnts in' governors for explosion engines. l The objects of this invention are,;first,'to rovide animproved s or explosion engines, y which, when the speed of the en e exceedsthe predeter minedrate', the a arging'of the 'englne is automatically pr vented, thereby preventing an explosion-andthereby controlling the speed. Second, to rovideanimprove governqr mechanism. or an exploslon engine, adapted to. disconnectthe electrical connections for the igniter mechanism when the speed of theengine ei'r'ceeds apredetermined raterv Third to provide an improved governor for explosion engines embodying. the above-advantages, which is very simple'in constructionand adjustment;

Further objects, and objects relating to structural details, will definitely appear om the detailed description to follow.

-I accomplish the objects ofmy invention by the devices and means described in the following specification.

When the speed of the 611". gine exceeds the predetermined or maximum rate at which the engine is set to run, the exhaust valve I is locked in its open positionby means of the finger carried by the slide or plunger 9. The s 'de or plunger 9 is arranged in the hollow spindle goftheactuating cam. A sp 9 which is arr-an ed within the hollow spindle to engage thisshde, holds the same normally. outward. This slide is connected to the collar Eon the crankshaft bymefansof the rod E which engages the outer end thereof. The rod E is ivoted at 6 its lower end engaging the colar.

mal position, the plunger, through the con maximum rate at which it is set, the, collar E is thrown outwardly by the governor weights, thereby releasing the slide g and allowing the finger g thereof to engage the exliaust valve stem, locking it out of its engag-' ing positionwith the cam and thus holding the valve open, so that no charge is taken into the engine until the speed again falls below the redeterminedrate. Then the governor ba ls dro back, disengaging the finger and allowing t 1e camand valve stem to enga e as before. By thus holding the exhaust va ve 0 en, cold air is drawn into and forced out of t e cylinder during the time that the engine is running above its normal predetermined rate, thereby cooling the valves and the engine cylinder, and wiping the same free of exhausted gases.

stem as it reciprocates, thereby making. and breaking the circuit through the metal parts of the machine. When the valve stem is locked out of'operation, as described, it is evident that the circuit remainsbroken. A second contact member K is carried by an adjustable plate K, which is secured'to the crank shaft casing by means of set screw's'lc,

arranged through a suitable slot is in the plate. As the cam G revolves it engages the contact member K, 'thereb causing and timingthe sparking, the timing being regulatedby the adjustment ofthe, plate, thereby adjusting the position of'the contact member gage it earlier or later in the stroke( It is apparent that no spark .takes lace except when the circuit is made througli the contact member J as described.

When the valve stem I. is locked out of operation by means of its connection to the overnor, the electrical connectlon 1s bro en;

thereby preventing thesparking duririg such perlod. This is of great advantage, in' that the electrical current is not needlessly exhausted. To vary the speed of the engine. the springs e of the flywheel are stiffened or,

relaxed. I By stiffening thespringit is necessary that the engine run faster in order to throw the governor balls out the required distance to allow the finger g to engage the. exhaust valve stem. Byrelaxmg the sprlngs the engine is caused to run slower, as it requires less speed to accomplish this result.

By my improved governor mechanism I i am enabled to run an engine w1th a minimum waste of fuel, and at the same time a minimum amount of electr city is used. I am enabled to control the engine sothat its 'speed is comparatively even. T he structure is very simpleand economical, and is very easy to adjust to change, the speed ofthe engine.

I have illustratedand described the same in detail in the form preferred by me on account 'of its structural slmplicity and the convenience with which it may be adjusted. ,I am,

however, aware that it is capableof consid 'erable structural variation withoutdepart-Q ingfrom my invention.
